IK4-IDEKO presents a project that seeks solutions to tackle problems during the grinding of slender shafts
When a grinding process has to be devised for a new part, certain quality specifications together with production outputs required by the customer have to be met; in those cases it is of vital importance to establish the optimal conditions as fast and straightforward as possible. Therefore, grinding of slender parts requires a more in-depth study and the application of different technologies that can facilitate find a solution to the difficulties in these cases.
Grinding is a process in the last stages of the
manufacturing of high-precision parts where demanding dimensional and surface
qualities are required. The process is based on removing excess material left
on the parts in previous processes with a rotating grinding wheel. The
elimination of the excess material occurs in the contact area between the wheel
and the workpiece, generating mainly normal forces that deform (bend) the
workpiece to a greater or lesser extent depending on the rigidity of the
system. In the case of thin parts, whose length/diameter ratios are high, the
rigidity of the system is far less and in order to obtain a quality part, the
forces exerted on the workpiece must be limited affecting the grinding
conditions and, consequently, productivity.
